Monolithic catalyst for simultaneous removal of NO_X and carbon particles, especially from off-gases of carbon power plants as well as the manner of production of the monolithic catalyst for simultaneous removal of NO_X and carbon particles, especially from off-gases of carbon power plants

摘要

A monolithic catalyst for simultaneous removal of NO_x and carbon particles, especially from off-gases of carbon power plants contains the monolith is made from acid-proof austenitic steel. The catalyst is a two-phase one; moreover, it contains the phases NiFe₂O₄ and Fe₂O₃(Mh) with spinel structure, and these phases form microcrystallites, additionally containing Mn.;The manner of production of the monolithic catalyst for simultaneous removal of NO_x and carbon particles, especially from off-gases of carbon power plants depends on the monolith is subject to oxidation after which the resulting oxide layers are washed with the solution of nickel salts; later the monolith is baked in the oxidising atmosphere with the view to inserting nickel ions into the oxide layer; finally this obtained oxide layers are subject to reduction.
